Both<\/span> Plavix<\/span><\/a> and<\/span> warfarin<\/span><\/a> are blood thinners doctors or healthcare providers often prescribe after a heart attack to lower the risk of stroke or another heart attack. However, they work on different parts of the clotting process and are approved for different conditions. Plavix is the brand name for clopidogrel, which works as a P2Y12 inhibitor that blocks platelets from clumping together. On the other hand, warfarin is a generic drug and vitamin K antagonist that blocks the production of blood clotting factors.\u00a0<\/span><\/p>\n

When comparing Plavix versus warfarin, it can be helpful to know some key differences between the two drugs, including forms, dosage, treatment plans, and who might benefit from taking the medication.<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

Is warfarin better than Plavix?<\/span><\/h2>\n

In many cases, it might not be right to say whether warfarin or Plavix is better since they\u2019re often used for different problems. \u201cGiven that Plavix and warfarin are prescribed for such different conditions, one cannot really consider one of these two medications to be \u2018better\u2019 or more effective than the other,\u201d explains <\/span>Matthew L. Holt, Pharm.D.<\/span>, a<\/span>ssistant professor of pharmacology at<\/span> PCOM (Philadelphia College of Osteopathic Medicine)<\/span><\/a>.<\/span><\/p>\n

For example, Plavix is approved to <\/span>prevent clots<\/span><\/a> and support healthy blood flow after a heart attack or ischemic stroke. Healthcare providers also prescribe it off-label with aspirin after a stent is placed in the heart. \u201cPlavix is often prescribed after a patient has received a \u2018stent\u2019 in one of their coronary arteries, and Plavix can help prevent blood from clotting around the stent,\u201d Dr. Holt explains.<\/span><\/p>\n

\u00a0<\/span>On the other hand, warfarin is typically prescribed to prevent or treat blood clots in conditions like venous thromboembolism, which includes <\/span>deep vein thrombosis (DVT)<\/span><\/a> and <\/span>pulmonary embolism (PE)<\/span><\/a>. \u201cThese clots are not generally caused by excess platelet activation but are caused by the tendency for blood to congeal, or \u2018coagulate,\u2019 when it is either moving very slowly, or not at all, in a large vein,\u201d Dr. Holt describes.<\/span><\/p>\n

Some people may do better on Plavix, while others respond more effectively to warfarin. The latter needs <\/span>more monitoring<\/span><\/a>, but it may be the right choice depending on what\u2019s being treated. Always consult a healthcare provider for a treatment plan that can give you the best results.\u00a0<\/span><\/p>\n

How long does it take for Plavix and warfarin to work?<\/span><\/h3>\n

Something else to consider is that each medication has a different timeline when it comes to how quickly its therapeutic effects occur, says<\/span> Joyce Oen-Hsiao, MD<\/span><\/a>, an associate professor of medicine at Yale School of Medicine.<\/span><\/p>\n

For example, Plavix is taken once per day<\/a>, and blood-thinning effects usually occur within four to 24 hours of starting the medication, according to Dr. Oen-Hsiao. But warfarin takes a little longer to thin the blood, usually not taking effect until three days after the initial dose, Dr. Oen-Hsiao says. If you\u2019re taking warfarin, sometimes you need to be put on another blood thinner like<\/span> heparin<\/span><\/a> or<\/span> enoxaparin<\/span><\/a> when you first start taking warfarin, until the warfarin begins to take full effect, she adds.<\/span><\/p>\n

Plavix vs. warfarin: Insurance coverage and cost comparison<\/span>\u00a0<\/b><\/h2>\n

If you\u2019re wondering about insurance coverage for Plavix or warfarin, there\u2019s good news.<\/span><\/p>\n

\u00a0<\/span>\u201cMost insurances, including Medicare and Medicaid, cover antiplatelet agents such as Plavix and anticoagulants such as warfarin,\u201d says<\/span> Hmoud Hosam, MD<\/span><\/a>, a cardiologist fellow at<\/span> Northwell\u2019s Lenox Hill Hospital<\/span><\/a>. \u201cBecause warfarin has been available for decades, it’s known to be a cheap and economical alternative should a patient have difficulty affording newer anticoagulant agents.\u201d Of course, insurance coverage isn\u2019t guaranteed, and there may be copayments or coinsurance payments that have to be met, depending on your insurance plan.\u00a0<\/span><\/p>\n

\u00a0<\/span>Plavix and warfarin are both available as generic medications, which makes them both relatively accessible. Without insurance, Plavix usually costs about $640 for a 30-day supply of 75 mg tablets. With a SingleCare savings card, the price can drop to<\/span> $4 for 30, 75 mg tablets of <\/span>generic Plavix<\/span><\/a>.<\/span><\/p>\n

\u00a0<\/span>Buying warfarin without insurance usually costs approximately $27 for 30, 5 mg tablets. However, with a SingleCare savings card, the price can be lowered to about $4 for 30, 5 mg tablets of <\/span>warfarin<\/span><\/a>.<\/span>\u00a0<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n

Warfarin vs. Plavix side effects<\/span><\/h2>\n

Warfarin and Plavix have possible side effects, some of which can overlap. Because they\u2019re blood thinners, both drugs carry a significant risk of severe bleeding, which may need immediate medical attention. People who take warfarin also need regular visits and follow-up checks to ensure it works well without causing bleeding.<\/span><\/p>\n

\u201cThe biggest side effect, or better termed adverse effect, is bleeding, which can sometimes be very dangerous,\u201d says<\/span> Mohanakrishnan Sathyamoorthy, MD<\/span><\/a>, professor and chair of internal medicine at Burnett School of Medicine at TCU. His recommendation? \u201cTaking fall risk precautions or being cautious with activities that could predispose one to falls is crucial,\u201d Dr. Sathyamoorthy says.<\/span><\/p>\n

However, even for bleeding, the medications can differ in terms of risk. \u201cWarfarin carries a higher risk of bleeding than Plavix, and, additionally, warfarin therapy has to be monitored by way of finger sticks or occasional blood draws to ensure that the risk of bleeding is not dangerously high,\u201d Dr. Holt says.<\/span><\/p>\n

Besides an increased risk of bleeding, other<\/span> warfarin side effects<\/span><\/a> include <\/span>nausea, vomiting, bloating, stomach pain, gas, and changes to your sense of taste<\/span>. In addition to bleeding, Plavix may also cause other <\/span>side effects<\/span><\/a>, including itching, diarrhea, stomach pain, and indigestion.<\/span><\/p>\n

Plavix and warfarin drug interactions and warnings<\/span><\/h2>\n

As blood thinners, Plavix and warfarin can interact with other drugs that have blood-thinning effects. These include other anticoagulants, antiplatelet medications, <\/span>nonsteroidal anti-inflammatory drugs (NSAIDs)<\/span><\/a>, and some antidepressants, such as <\/span>selective serotonin reuptake inhibitors (SSRIs)<\/span><\/a>.<\/span><\/p>\n

When it comes to<\/span> Plavix interactions<\/span><\/a>, certain medications may decrease the effectiveness of Plavix, including<\/span> proton pump inhibitors (PPIs)<\/span><\/a> and<\/span> calcium channel blockers (CCBs<\/span><\/a>). However, warfarin generally has more drug interactions than Plavix. For example, warfarin can interact with <\/span>various antibiotics<\/span><\/a>, antifungal drugs, herbal supplements, and other products that can either increase the risk of bleeding or make warfarin less effective at preventing clots.<\/span><\/p>\n

Since the benefits of taking warfarin or Plavix generally outweigh the risks, there are very few groups of people who should avoid taking these medications if they\u2019re needed, Dr. Holt says. Both Plavix and warfarin shouldn\u2019t be taken if you are pregnant, and you should ask your provider about the safety of these medications while breastfeeding. Additionally, \u201cpatients with a low platelet count at baseline should either avoid these medications or be monitored by their physician meticulously,\u201d Dr. Hold advises.<\/span><\/p>\n

Plavix and warfarin food interactions<\/span><\/h3>\n

While Plavix doesn\u2019t generally have food restrictions, warfarin can interact poorly with foods that you may be eating. \u201cWarfarin interacts with foods high in vitamin K, especially green, leafy vegetables, such as kale, spinach, mustard greens, asparagus, and broccoli,\u201d Dr. Oen-Hsiao says. But this doesn\u2019t mean you have to avoid these foods entirely.<\/span><\/p>\n

\u201cIn the past, patients were told to avoid all green leafy vegetables; however, now we encourage patients to be consistent with how many vegetables they eat weekly,\u201d Dr. Oen-Hsiao explains. Sometimes, the warfarin dosage is adjusted based on your dietary pattern, Dr. Oen-Hsiao adds.<\/span>\u00a0<\/span><\/p>\n

We all have different health issues and specific patient needs. The best way to manage them is to consult a healthcare provider who can explore different options and find the right blood thinner for you.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
